I have just purchased the EPS Super Record Titanium groupset and have had a number of issues in the first week:
1. A lot of chain slap which would have caused considerable damage to the chainstay but i mounted a guard from the start.
2. Had a case of chain suck where the chain on move from 39 -> 53 got stuck between rings causing considerable damage to the frame (chain stay) right down to the carbon fibre, all paint gone

3. Have had problems on a few training spins where the gearing doesnt change after selection, hitting the button again and the chain will jump two gears at once.
4. Have had the white light come on, on the power unit which indicates a power unit fault. According to Campagnolo this can be reset once and if it comes on again i will have to look for service under warrenty. (This actually reminds of the X-Box red ring of death which i have also had this summer)
ALL THIS IN THE FIRST WEEK

Some background : I am in my 30th season of racing, i have a Lapierre x-lite 999 with campagnolo c-record on it from 2005, the frame is still immaculate, never had a problem with chain suck before.
The new EPS is mounted and adjusted professionally on a brand new Colnago C59.
Has anyone else had similar problems?
I was considering staying with the mechanical groupset for this particular reason that at least if anything happened i could fix it myself or swap out a part without having to leave it in and be without. Starting to regret my decision of going for the EPS system now.
